Introducing the Industry's Lowest Voltage MCU
 AC Current Sensors
The Si85xx products are unidirectional ac current sensors available in full-scale ranges of 5, 10 and 20 A. Si85xx products are ideal upgrades for older current-sensing technologies offering size, performance and cost advantages over current transformers, Hall effect devices, DCR circuits and other approaches. With its 4x4 mm footprint and 1 mm height, the Si85xx is among the smallest current sensors available.
